Nonperturbative Mellin Amplitudes: Existence, Properties, Applications
Joao Penedones, Joao A. Silva, Alexander Zhiboedov
We argue that nonperturbative CFT correlation functions admit a Mellin amplitude representation. Perturbative Mellin representation readily follows. We discuss the main properties…
The light-ray OPE and conformal colliders
Murat Kologlu, Petr Kravchuk, David Simmons-Duffin +1
We derive a nonperturbative, convergent operator product expansion (OPE) for null-integrated operators on the same null plane in a CFT. The objects appearing in the expansion are l…
Energy-energy correlations at next-to-next-to-leading order
Johannes M. Henn, Emery Sokatchev, Kai Yan +1
We develop further an approach to computing energy-energy correlations (EEC) directly from finite correlation functions. In this way, one completely avoids infrared divergences. In…
Shocks, Superconvergence, and a Stringy Equivalence Principle
Murat Kologlu, Petr Kravchuk, David Simmons-Duffin +1
We study propagation of a probe particle through a series of closely situated gravitational shocks. We argue that in any UV-complete theory of gravity the result does not depend on…
